背景技术背景：国际研究表明，12-58%的针对运动和从事体育运动的人的膳食补充剂含有世界反兴奋剂条例（WADC）禁止的物质。在某些情况下，兴奋剂物质没有在产品标签上声明，因此消费者可能不知道他/她摄入了什么。材料和方法：为了调查挪威市场上销售的膳食补充剂中兴奋剂物质的流行情况，对挪威消费者在线商店的93种高风险产品进行了WADC禁用清单上的物质和药物分析。所有的补充剂都被销售为能够提高能量水平和/或具有肌肉建设或脂肪燃烧效果。根据收到的提示，在线论坛和/或国际lists.Results的基础上选择的产品：共21 93（23%）的产品分析含有违禁物质，药物和/或非法数量的咖啡因。在93种膳食补充剂中的8种（9%）中检测到WADC禁用清单上的物质。所有含有兴奋剂物质的产品都被宣布含有一种或多种禁用物质。解释：结果表明，使用在针对挪威消费者的网上商店购买的明显法律的膳食补充剂涉及无意中使用兴奋剂和不良健康影响的风险。
BACKGROUND: International studies have shown that 12-58% of all dietary supplements intended for people who exercise and engage in sports contain substances prohibited by the World Anti-Doping Code (WADC). In some cases, the doping substances are not declared on the product label, and the consumer may therefore be unaware of what he/she ingests. Many of the substances may cause adverse health effects, and sale of such products is illegal in Norway.MATERIAL AND METHOD: To investigate the prevalence of doping substances in dietary supplements sold on the Norwegian market, a total of 93 high-risk products from online shops targeting Norwegian consumers were analysed for substances on the WADC Prohibited List and pharmaceutical drugs. All supplements were marketed as able to boost energy levels and/or having a muscle-building or fat-burning effect. The products were selected on the basis of tips received, online forums and/or international lists.RESULTS: Altogether 21 of 93 (23%) products analysed contained prohibited substances, pharmaceutical drugs and/or illegal amounts of caffeine. Substances on the WADC Prohibited List were detected in 8 of the 93 (9%) dietary supplements. All products containing doping substances were declared as containing one or more banned substances.INTERPRETATION: The results show that using apparently legal dietary supplements purchased in online shops targeting Norwegian consumers involves a risk of inadvertent doping and adverse health effects.
